摘要： An actuator includes a movable member that, when moving, abuts against a key (performance operator) to move the key. A first sensor detects motion of the key. A second sensor detects motion of the movable member. A processor determines, based on outputs of the sensors, whether or not the key and the movable member are currently in a mutually separated state. When the key and the movable member are in the mutually separated state, the processor controls the actuator in such a manner that the key and the movable member are in contact with each other. When the key and the movable member are not in the mutually separated state, the processor controls the actuator by use of feedback information based on the output of the first sensor, whereas, in the mutually separated state, the actuator is controlled by feedback information based on at least the second sensor output.

摘要： An elongated lifting rail is displaceable to collectively pivot a plurality of damper levers. An actuator is provided beside or underneath the lifting rail for automatically displacing the lifting rail. The lifting rail is displaced, in response to driving of the actuator, to displace the damper levers so that the dampers are moved away from contact with sounding members. Further, a position sensor is provided for detecting a displaced position of the lifting rail, so that position data detected by the position sensor is used for operating position control and/or operating position recording of the dampers.

摘要： In a player piano, a position sensor is provided on an end portion of a lifting rail for detecting a vertical position of the lifting rail. In storing performance data of dampers, a signal output from the position sensor and indicative of a vertical position of the lifting rail is converted into a digital signal, and a position value indicative of the position of the lifting rail is generated on the basis of the digital signal and stored into a buffer. A conversion section converts the position value into a vertical position of a pedal rod connected to a damper pedal, and the thus-converted vertical position is converted, into a control value which a control change message of the damper pedal in MIDI-format data can take. The control value obtained in the aforementioned manner can be recorded into a recording medium as performance information.
